Abstract
A multilevel security attribute passing system on a computer operating under a multilevel operating system engaged in stream communications and enabling contemporaneously opening a plurality of sockets having the same port number while meeting the requirements of a predetermined security policy. The security attributes of received data are copied into a credentials structure identified by a pointer in an attribute structure. The security of a data node configured for data stream communication is specified by storing the security attributes of transferred data into a selected data structure and then pointing to the selected data structure with intervening transmission and attribute structures.
